The thermometer which has been used latterly, is one of Pasto- 

 relli's spirit thermometers, which registers the lowest temperature. 

 (Unfortunately the registering day thermometer was broken in bring- 

 ing it to this country.) The barometer is one which was purchased 

 in Liverpool in 1827, calculated for measuring heights. That it is 

 quite accurate, I am not prepared to say : during my absence in Eu- 

 rope, it fell and the glass tube was broken ; since my return, I have 

 replaced it, taking care to purify the mercury and boil it in the tube. 

 But, as it is the first barometer I ever attempted to construct, I fear 

 it may not be quite free from air ; indeed, in comparing my baro- 

 metrical observations with those of Mr. Redfield, I must believe, 

 that mine are too low, or else, there must be a remarkable difference 

 between the indications of the instrument, here and in New York. 

 However, such as they are, I shall give them ; they will serve, at 

 all events to show the range, and you can make use of them, or not 

 as you please :
